Question

Oludonts c) 2x + y = 2
2x + 2y = 0​

Answer 1

`x = 2`

`y = -2`

Explanation:

Given

`2x + y = 2`

`2x + 2y = 0`

Required

Solfe for x and y

Subtract both equations

`2x- 2x + y - 2y = 2 -0`

`-y = 2`

Divide by -1

`y = -2`

Substitute
`y = -2` in
`2x + 2y = 0`

`2x+2 *-2 = 0`

`2x-4 = 0`

`x - 2 = 0`

Collect like terms

`x = 2`
